A mbr deploys on Op Impact to Kuwait. He spends more than 30 days there, qualifying for a GSM-EXP.
He then covers off a position in Iraq for over 30 days, qualifying for GCS-EXP, returning to Kuwait.
He then gets extended in Kuwait, such that he's there for at least 210 days, which is at least 180 days after he first qualified for the GSM but less than 180 days after he qualified for the GCS.
Does he qualify for both the GSM and GCS?

"The GCS and GSM recognize 30 cumulative days (5 sorties for ALLIED FORCE ribbon of the GCS) provided that the service has not been recognized by another service medal."
I've been hearing about going 180 days past qualifying for one medal allowing the award of both, but I'm finding nothing clear on the chart. If he'd spent all of his time in one country, he'd have had a bar.

WITH THE NEW PRINCIPLE OF ROTATION RECOGNITION, THE EXISTING PROVISION STATING THAT ONE CANNOT EARN BOTH THE GCS AND GSM IN RESPECT OF THE SAME OP IS AMENDED SO THAT IT IS NOW POSSIBLE FOR A PERSON TO EARN AND WEAR BOTH THE GCS AND THE GSM FOR A GIVEN THEATRE AS LONG AS THE PERSON DOES NOT MEET THE CRITERIA FOR BOTH DURING THE SAME 6 MONTHS PERIOD. WHEN A PERSON MEETS THE CRITERIA FOR THE GCS-SWA OR A BAR TO IT AND THE GSM-SWA OR A BAR TO IT WITHIN A PERIOD OF 180 DAYS, THE PERSON SHALL ONLY BE AWARDED THE GCS OR A BAR TO IT"
So here's where the 180 days seem to come in. I'm still not sure if the mbr would qualify for both.
